[The doubled symbols are used when we need to perform an operation on one number and one "real number" or two "real numbers"; we must use standard symbols to operate on two numbers. The use of the doubled symbols improves readability with easing equations, which often need to use fractional values.]

To decide which real number is (A - value) ++ (B - value):
decide on A real plus B.

To decide which real number is (A - value) -- (B - value):
decide on A real minus B.

To decide which real number is (A - value) ** (B - a value):
decide on A real times B.

To decide which real number is (A - value) // (B - a value):
decide on A real divided by B.

To decide whether (A - a value) << (B - a value):
if A is real less than B, decide yes.

To decide whether (A - a value) >> (B - a value):
if A is real greater than B, decide yes.

To decide which real number is (A - value) ^^ (B - value):
decide on A to the power B.

To decide which real number is sqrt (A - a value):
decide on the real square root of A.
